Currently different firmware drivers search the /firmware/ node and populate the sub-node devices selectively. Instead we can populate the /firmware/ node during init to avoid more drivers continuing to populate the devices selectively. To generalize the solution this patch populates the /firmware/ node explicitly from of_platform_default_populate_init().
